Button batteries (also called coin batteries) are small, shiny, and easy to overlook but they can be extremely dangerous if swallowed or placed in a child’s nose or ears. These batteries are found in many everyday household items, including toys and electronics, making awareness especially important for families with young children.
What Are Button Batteries?
Button batteries are small, round batteries commonly used in:
- Toys and light-up books
- Remote controls
- Musical greeting cards
- Watches
- Flameless candles
- Thermometers and hearing aids
Because they’re easy to access and look harmless, children are naturally drawn to them.
Why Are They So Dangerous?
If swallowed, a button battery can cause serious internal burns in as little as two hours. The battery creates a chemical reaction that can severely damage tissue, even if it’s considered “dead.”
This can lead to:
- Internal burns
- Bleeding
- Long-term injury
- In severe cases, life-threatening complications
Immediate action is critical.
Signs a Child May Have Swallowed a Button Battery
Symptoms aren’t always obvious, but may include:
- Drooling
- Trouble swallowing
- Vomiting
- Chest or stomach pain
- Coughing or gagging
- Unexplained irritability
If ingestion is suspected, seek emergency medical care immediately.
How to Reduce the Risk at Home
Simple steps can make a big difference:
- Choose toys with secured battery compartments (screws, not snap-open backs)
- Store spare batteries locked away and out of reach
- Dispose of used batteries safely — they can still be dangerous
- Regularly check remotes, toys, and small electronics for loose battery covers
- Be extra cautious during holidays, when new toys and greeting cards enter the home
What To Do in an Emergency
If you believe a child has swallowed a button battery:
- Call 911 or go to the nearest emergency room immediately
- If advised by medical professionals, honey may be recommended for children over 1 year old while en route — but do not delay emergency care
Always follow guidance from medical professionals.
A Quick Reminder for Caregivers: Button battery safety isn’t just for parents. Babysitters, grandparents, teachers, and anyone caring for young children should be aware of the risks and check their environments regularly.
